TRANSMISSION BAND.

To all whom it may con 0cm:

Be it known that I, GLENN R. HOFFMAN, a citizen of the United States,residing at Springfield, in the county of Sangamon and State ofIllinois, have invented certain new and useful Improvements inTransmission Bands; and I do declare the following to be a full, clear,and exact description of the invention, such as will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters andfigures of reference marked thereon, .which form a part of thisspecification. I

My invention relates to transmission bands, and has for its object toprovide improved features of construction in the removable ear whichwill permit of its application and removable to and from the band forfacilitating the removal of the transmission band from the transmissionfor needed repairs or other purposes and its replacement thereon Withoutinterference with the transmission gears, say of the type used in theFord car or truck. To the accomplishment of the foregoing and such otherobjects as may hereinafter appear the invention consists in the featureshereinafter particularly described and then sought to be clearly definedby the claims, reference being had to the accompanying drawing forming apart hereof, and in which Figure 1 is a perspective of the removableear, detached;

Figure 53 a perspective of a portion of the transmission band;

Figure 15 a central longitudinal section through the ear and portion ofthe metallic strap or band and its lining.

In the drawing the numeral 1 designates the removable ear of atransmission band, the other ear which is usually permanently attachedto one end of the band not being illustrated as it is constructed andapplied in the customary manner and therefore iieed not be illustrated.The removable ear illustrated has its shank portion formed with slots 2which are enlarged at one end and also formed on its under face at thenotched end of the ear with a depending shoulder or member 3. The bandto which this ear will be detachably secured comprises a 'metallic strapor band 4 having a lining 5- ofwoven fabric or othersuitable material,

and headed studs 6 projecting from the 'band i and designed to be passedthrough the slots 2 of the ear. The end of the band 4 next to thenotched end of the ear is formed with a recess 7 designed to receive theshoulder or member 3 when the ear is in set position on thehand so thatwhen the band is applied to its drum and the two ends are drawn to-Wards each other by usual means employed for the purpose, the end of themetal strap portion 4 will abut against the shoulderror member 3 andlongitudinal slipping ofthe ear on the band prevented. To apply [the earto the band, the ear is positioned so that, the headed studs Will passthrough the enlargements of the slots 2 and then the ear is slipped inthe direction of the free end of the band so as tobring the headed studsinto the narrower portions of the slots and the shoulder or member 3into the recess 7 of the metal'strap portion 4 of the band, theengagement of the heads of the istuds with the upper face of the shankof the ear tend:

ing to prevent the separation. or spreading apart of the ear and band,and longitudinal slipping of the ear in one direction prevented byengagement of the stu'dswith the end walls of the narrow portions of theslots, and movemept' in the other dire tian prevented by engagement ofthe shoulder or member 3 with the end of the metal band 4 where it liesin the recess formed therein. To remove the ear the metal strap or bandand its lining is depressed next to the notched end of the ear todisengage the band from the shoulderor member 3 and then the ear is slidendwise to bring the heads of the studs into register with theenlargements of the slots 2 when the ear is slipped from attachment tothe band.
